UFC officials Wednesday announced the matchup, which takes
place at San Antonio’s AT&T Center and precedes a titular
featherweight headliner between Cub Swanson
and Jeremy
Stephens.

Gastelum, 22, has been perfect as a pro through eight outings,
scoring a split decision victory over the favored Uriah Hall to
win “TUF 17” one year ago. Following his auspicious Octagon debut,
Gastelum followed the performance with two more victories, stopping
Brian
Melancon last August before outpointing Rick Story
last month at UFC 171.

Musoke, 28, has won seven of his last eight, with a 2012 no contest
serving as his only blemish in that span. The Swede submitted
veteran Alessio
Sakara in his UFC debut this past October and then posted a
unanimous decision victory in his sophomore effort, besting
Viscardi
Andrade this past February at UFC Fight Night 36.
